Toxic effect of contact w unsp venom animal, assault, init

This code signifies a harmful reaction resulting from direct contact with an unidentified venomous creature, where the exposure was intentionally inflicted by another party. The patient is experiencing the initial phase of this toxic effect.

Apply this code when documentation clearly indicates a patient presenting with symptoms of envenomation (e.g., pain, swelling, systemic reactions) due to an assault by an unspecified venomous animal. This is appropriate for the initial visit or active treatment phase of the injury.

• Ensure the medical record explicitly states the venomous animal was "unspecified" and the encounter was an "assault."
• Do not use this code if the type of venomous animal is known; instead, select a more specific T63.x code.
• Always append the appropriate seventh character for subsequent encounters or sequelae.
